passive wastewater treatment Articles

After a homeowner’s septic system failed on a small lot and the homeowner was faced with a large bill for a new system, Virgil Russon of Greeley, Colo., looked for a solution. He did extensive research for alternatives to pipe and stone, and found Advanced Enviro-Septic (AES). The AES System provides advanced treatment of septic effluent to tertiary quality, is completely passive with no ...

The occurrence and the partitioning of polycyclic aromatic hydrocarbons (PAHs) and seven metals (Al, Cd, Cr, Cu, Ni, Pb and Zn) were investigated in activated sludge wastewater treatment plants by means of passive and active sampling. Concentrations total dissolved and particulate contaminants were determined in wastewater at several points across the treatment system by means of grab sampling. ...

THE TERM, “decentralized waste-water management,” refers to the process of treating and discharging treated wastewater in the local vicinity where it is generated. Decentralized systems typically use the soil as the final receptor of the treated wastewater instead of discharging to surface waters, which are generally the receptors of treated wastewater from larger centralized treatment plants. ...

THE CHALLENGE Prichard AL is a town of about 30.000 people north of Mobile. AL Paul David, the Sewer Board Superintendent, oversees the contract management of two (21 ...

Passive liquid surfaces in wastewater treatment plants may be potential sources of odorous emissions. This study investigates the occurrence and significance of deviations that may originate from the use of the effective diameter as fetch parameter in the empirical correlations utilised by the WATER9 model to estimate odorous emissions at passive liquid surfaces. A sensitivity analysis was ...

Pharmaceuticals are ubiquitous in surface waters as a consequence of discharges from municipal wastewater treatment plants. However, few studies have assessed the bioavailability of pharmaceuticals to fish in natural waters. In the present study, passive samplers and rainbow trout were experimentally deployed next to three municipal wastewater treatment plants in Finland to evaluate the degree of ...

A Clearcat evaporator at KSB in La Roche Chalais (France) for the treatment of industrial wastewater on site. The KSB factory at La Roche Chalais (24), a subsidiary of Germany's KSB AG, manufactures AMRI brand butterfly valves. These valves are used in the construction, industrial, water, and electric power generation sectors. The production of these valves generates two main liquid wastes: ...

Abstract: Effluent filters are installed in the outlet from the septic tank with the intended purpose of retaining solids inside the tank, preventing them from entering the treatment system and/or dispersal field. The concern is that if solids escape from the septic tank, they could cause clogging of the system components or the soil interface. While this may be a legitimate concern for some ...

Blodgett Landing Treatment Plant Cluster System for Passive Community Treatment with Denitrification The Blodgett Landing Treatment Plant is a 50,000 GPD facility that provides passive advanced treatment and dispersal with denitrification. The town of Newbury chose the passive Enviro-Septic® System to meet strict treatment levels with a small budget. They had to ...

Customer: Brew Creek Lodge, BC, Canada A tale of two wineries. Two regions. Thousands of miles apart. Vastly different as winemaking regions but united by a singular commitment to quality and innovation. In both Niagara and the Okanagan, Inniskillin offers a full collection of fine VQA wines made by dedicated winemakers and viticulturists committed to their craft. Building on that ...

ABSTRACTConstructed treatment wetlands have become an established technology for treatment of municipal and industrial wastewaters around the world. Wetland systems can provide treatment similar to conventional tertiary wastewater facilities if sufficient land is available but with lower energy and maintenance requirements. Ancillary benefits of treatment wetlands include wildlife habitat, ...

Customer: Inniskillin Winery Niagara region, ON, Canada A tale of two wineries. Two regions. Thousands of miles apart. Vastly different as winemaking regions but united by a singular commitment to quality and innovation. In both Niagara and the Okanagan, Inniskillin offers a full collection of fine VQA wines made by dedicated winemakers and viticulturists committed to ...

Biosorption is a process of metabolism-independent, passive, physico-chemical binding of metal ions involving non-living biomass, which offers advantages over conventional methods because of cost-effectiveness, especially for dilute metal solutions, and minimal environmental impact. This paper reviews heavy metal biosorption using silvichemical-based biomass materials. It discusses the use of a ...

Customer: Municipality of Saint-Joseph-de-Kamouraska County of Kamouraska, QC, Canada Located approximately 180 kilometres East of Quebec City, and 20 km (12.5 mi) from Rivière-du-Loup, the municipality of Saint-Joseph-de-Kamouraska is part of the Bas-Saint-Laurent Administrative region. Founded in 1922, its economy is based primarily on agriculture and lumber. This peaceful rural ...

Introduction In 1993, Olmsted County installed an advanced individual sewage treatment system (ISTS) at the caretaker's residence at a County-owned park to demonstrate waste load reduction and downsizing of drainfield area. The subject system has two components--1) a composting/vermiculture blackwater system and a 2) aerobic graywater treatment system. The separation of the high strength ...

A cocopeat biofilter system is a low-cost and low-maintenance on-site wastewater treatment solution that is modular in design and applicable for residential, institutional and commercial establishments. The system can be designed to passively treat septic tank effluent to meet secondary treatment levels. For residential use, the biofilter unit consists of a relatively small ...

Use of Managed Aquifer Recharge (MAR) has rapidly increased in Australia, USA, and Europe in recent years as an efficient means of recycling stormwater or treated sewage effluent for non-potable and indirect potable reuse in urban and rural areas. Yet aquifers have been relied on knowingly for water storage and unwittingly for water treatment for millennia. Hence if ‘leading edge’ is defined as ...

ABSTRACTTransient or intermittent releases of specific volatile or semi-volatile organic compounds are not managed well by existing predictive fate models such as TOXCHEM+ or Water9 because they are based on steady-state conditions. In this paper, two scenarios for treatment of transient organic compound concentrations are studied using dynamic simulation: ...

Most of the regulations applicable for onsite wastewater treatment system are based on the use of native soil for effluent dispersal. However, there are more and more situations where dispersal of effluent in native soil is impossible: repairs of existing systems on undersized lots for implementation of required dispersal fields: sites located in soils having low permeability: or where the ...
